The purpose of venting is to get the attic space as close to ambient temperature as possible. Most attic spaces in Thailand are sealed tight as a box, and hot as a sauna.

Has anyone tried venting ( and insulation ), and what was the result?

 

Thanks. 

We have gable vents at both ends of each roof space (with bug screens). With the wind right it howls through.

 

Insulation on the ceiling seems to work reasonably well, but I don't have an uninsulated space to compare.

All the houses in the surrounding villages with roofs where they are appropriate have gable vents

Vents, foil under the tiies, insulation on the ceiling, close the doors and windows early.
